IMPROVEMENT IN LAClNG-BUTTGNS.' f

To all 'whom it 'may concern:

Beit known that I, DAVID HEAroN, of the city and county of Providence and State of Rhode Island, have invented certain Improvements in .LacingButtons and similar devices for Lacing Wearing Apparel, of which the following is a specification, referring to the accompanying drawing making part of the same, in which-- ,y

Figure lis a side elevation of my improved lacingbutton5 Fig. 2 is a front elevation of the same 5 Fig. 3 is a rea-r elevation; Fig. is a front elevation of a vertical section of the same; Fig. 5 is a view of the under side of the button-head; Fig. 6 is a view of the back side of the material with the fastening-prongs lof the button clinched thereon; and Fig. 7 is a view of the blank from which said improved lacing-button is made.

Similar letters mark like parts in all the figures. v

The invention hereinset forth relates to an improvement in the construction of the lacingbutton patented by me July 16, 1872, by Letters Patent No. 129,474, to which reference is to be had for theconsideration of this matter. 'Ihe first part of thel invention relates to the improvement of the button-head of tlie lacing device; and consists in inserting the edge of the under part ofthe buttons head within the periphery of the upper part of the same, to

make a smoother andbetter finish at the edge.

The second part of the invention consists in making the neck tapering from the base to the head, to stiften and strengthen the neck at the base so that it will resist the lacing strain more effectually. The third part of the invention consists in constructing the lacing-button with one fastenin g-pron g in front and two fastenin g-pron gs at the rear, by the neck, to fasten the button firmly at the base of the neck and for the sake of greater economy` in stock,con sidering the form of the blank.

In the drawing, a is the upper part and bis the under part of conveXo-concave buttonhead H. The under part bis made smaller than a, as shown in the blank7 Fig. 7, and after being slightly concaved is doubled at o,

' and the under part b is let into the concavity of the upper part a, as shown in Figs. 4 and 5, leaving only the outer edge a of the upper Specification forming part of Letters Patent No. 133,@5?, dated December l0, 1872.

neck I' of the button is formed by bending the part e of the blank, Fig. 7, against the part g, and connin g both together by bendingthe two clasping parts i t" around both e and g; and it will be observed that the neck part c, from theA base B tog the head H, and that the clasping parts i are cut at an angle to embrace this tapering pa-rt c, and form the tapering neck shown in Figs. 2, 3, and 4. By this construction the neck is greatly stifened at its junc tion with the base B, so that breaking or even bending at this point is entirely obviated. Thel set of three fastening-prongs are arranged one in front on the base-plate B, and two, d2 and d3, at the rear, on each side, beneath the neck. The front prong d1 is in line witlrthe space between the two rear prongs d2 cl3, and they are in line with each other edgewise across the rear of the button, as shown in Figs. l, 2, 3, 4, so that when bent and clinched together on the back side ofthe material, as shown in Fig. 6, the ends of the prongs lap by each other with the front prong d1 between the ends of the other two; or the two rear prongs d2 and d3 may be bent backward instead of forward from the rear of the neck, as shown in dotted lines, Fig. 6, and thereby obtain a rmer hold, and furnish additional resistance to the lacing strain, or a tendency to tear out of the material.

As shown in the drawing, the two rear prongs d2 cl3 are cut from the end of the blank or continuation of the part g, which forms the neck; butsaid rear prongs can also be cut from the material at the rear of the base-plate B on each side, in the same relative position -with the front prong, as shown in' Fig. 12, and capable of being clinched to fasten it in the material in the same manner as hereinbefore described. In like manner there may be one prong, d1, at the front and another single prong, d, at the rear in place of the two d2 d3, by simply changing the form of the rear end of the blank to that shown in full lines in Fig. 11; and said single rear prong el may be formed with a notch, e, inthe end to receive the beve1- point t of the front prong, when the two are showing the rear prong d extending down from the base of the tapering neck, and with a wide base-plate B to support the button laterally. The single rear prong d is shown bent backward from the rear of the neck, and clinched on the back side of thefmaterial, in the dotted lines of Fig. l0; and both constructions and arrangements of the prongs are applicable to lacing devices of different constructions, with the advantage of a considerable saving in stock, owing to the snug and compact form of the blank by the peculiar arrangement of the fastening-prongs, as shown and described in line parallel, or nearly so, with the body of the blank, instead of extending radially therefrom, as in the patent referred to, and in some other cases.

Having described the several features of my invention, I claim- 1. The construction of the button-head II with the under part b inserted within concave periphery oi the upper part a, substantially as shown anddescribed.

2. The tapering neck I, from the base B to the head H of Athe lacing device, substantially as shown and described.

3. The construction and also the arrangement of a set of three fastening-prongs, with one prong in front in the middle, and two prongs at the rear on each side beneath the neck, with the mode of clinching the same, substantially as shown and described.

4. The construction and also the arrangement of a set of two fastening-prongs, with one prong in front and the other prong at the rear of the neck Yin line with the one in front, with provision for clinching the same, substantially as shown and described.

5. The mode of forming the three fasteningprongs described bycutting them in line parallel with the body of the blank, substantially as shown and described.
